Comment (by mrkapqa):

 the error shown in "mpv -v" is the following

 [vo/gpu] Probing for best GPU context.
 [vo/gpu/opengl] Initializing GPU context 'cocoa'
 Assertion failed: (group_index >= 0), function
 m_config_cache_alloc_internal, file ../options/m_config.c, line 1461.
 Abort trap: 6


 maybe the error is related to the graphics card NVIDIA GeForce 9400 or
 maybe i need to -re-configure mpv with X11 variant?
